If you didn't have to worry about the cost what would you like for a hobby?

Collecting antique muscle cars?

The biggest model railroad layout I could have.

wood turning and cabinet making..

If I had enough money that I didn't need to work anymore, I would like to get back to playing the piano and practice for hours each day so I could get back to the skill level that I was at in high school, and once I learned enough, maybe I could entertain people in nursing homes or other places where people could use some entertainment. If I had enough money, I could just play for free, just for the joy of playing and bringing joy to others.

Large mostly self sufficient freshwater aquariums.

Collecting awesome muscle cars.

A complete landscaping renovation...I've always wanted a proper English garden ... something you'd see at a quaint cottage

Amateur League drifting 😃 it's so much fun! Tires fuel and constant part replacement gets amazingly expensive 😫

Photography

Toppling governments

Either cars or world travel.

It's not always the money...it's the time and patience....I'd love to paint. Being on a beach or some scenic overlook....or having a cool studio that's a mess w/canvases and paint. I'm kind of a neat freak so this would totally go against my grain.

Traveling.

Take my time travelling and getting to know people.

Some sort of martial art or yoga so I could be more limber

Raising alpaca & sheep and making yarn

Flying jets, yachts and skis.

Fine jewelry making

ultra light flying.

Space travel

My current hobby.
Music stuff gets expensive... 😰
